Ashcroft 94595XLL Pressure Gauge 0-30 Psi 3.5in Dial

Product Description

The ASHCROFT 94595XLL is an industrial-grade analog pressure gauge designed for accurate pressure monitoring in a wide range of fluid and gas systems. It covers a measurement range of 0 to 30 psi with 1% of scale accuracy, making it suitable for applications where reliable readings are required without the complexity of a liquid-filled gauge. The 3.5-inch dial provides clear readability at a distance. The stainless steel case — available in grades 304 and 316 — and bronze wetted parts deliver solid corrosion resistance. The polycarbonate lens protects the dial from dust and moisture ingress. Licensed plumbers, HVAC technicians, and industrial maintenance professionals are the typical installers of this gauge.

This gauge fits lower-mount installations and connects via a 1/4-inch MNPT thread. It is suited for residential and light commercial plumbing, HVAC, and industrial process applications where pressures remain at or below 30 psi. The no-fill design keeps installation and disposal straightforward in environments where liquid-filled gauges are unnecessary or restricted. Certifications include CRN, IP54, IP65/NEMA 4, PED, and RoHS compliance, supporting use in both standard and environmentally demanding service conditions.

Key Features

• Stainless steel case (grades 304 and 316) for corrosion resistance
• Bronze wetted parts compatible with a broad range of media
• No-fill design simplifies installation and meets restrictions on liquid-filled gauges
• Polycarbonate lens with IP54 and IP65/NEMA 4 ratings for dust and moisture protection
• CRN, PED, and RoHS certified for multi-jurisdiction compliance

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for industrial, HVAC, and plumbing systems requiring a 1/4-inch MNPT lower-mount connection and a 0 to 30 psi measurement range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or industrial mechanic. Always shut off system pressure and relieve residual pressure from the line before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the MNPT threads per the applicable piping code (IPC or IFGC) before threading into the port — do not overtighten, as this can damage the brass socket. Verify that the system operating pressure does not exceed the gauge maximum to prevent dial damage or seal failure.
